interPhaseChangeDyMFoam
|
|
|
|
Description
|
|
Solver for 2 incompressible, isothermal immiscible fluids with phase-change
|
|
(e.g. cavitation). Uses a VOF (volume of fluid) phase-fraction based
|
|
interface capturing approach, with optional mesh motion and mesh topology
|
|
changes including adaptive re-meshing.
|
|
|
|
The momentum and other fluid properties are of the "mixture" and a
|
|
single momentum equation is solved.
|
|
|
|
The set of phase-change models provided are designed to simulate cavitation
|
|
but other mechanisms of phase-change are supported within this solver
|
|
framework.
|
|
|
|
Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
